Abstract: A wall system comprising at least one wall module and at least one linking element is provided. Said wall module comprising a substantially rectangular plate (3), said rectangular plate comprising two side edges (5a, 5b), each comprising a side edge bent configuration (11), wherein said side edge bent configuration comprises a first side bend (13a), a second side bend (13b) and a third side bend (13c), wherein all three side bends (13a,b,c) are substantially 180° or 160-200° and are provided along different bending lines being parallel with the side edges (5a, 5b) of the plate.

Abstract: A pipe shaft module and a method for mounting a pipe shaft module in a pipe shaft of a building, said pipe shaft module (1) comprising: —a pipe connection box (5); and—at least one pipe (7a, b, c) which is protruding into the pipe connection box (5) and which is provided to the pipe connection box such that it can slide along its length direction in relation to the pipe connection box, wherein said pipe connection box (5) comprises: —a pipe connection device (11) comprising at least one pipe connector (13a, b, c) for each pipe (7a, b, c) provided in the pipe shaft module (1), wherein said pipe connection device (11) is mounted within the pipe connection box (5) such that it can be moved within the pipe connection box (5) into at least two different positions where one position is a connection position in which the pipe connectors (13a, b, c) are positioned such that one pipe connector (13a, b, c) can be connected to each pipe (7a, b, c) of the pipe shaft module (1).
